Saint Sulpice la Foret : a 1000 PE waste stabilization pond boosted to 1950 PE by addition of reed bed filters. A 2,400 m², vertical flow reed bed (French system), a 1,950 m² second stage vertical flow, unsaturated plus a 10,000 m² of willow plantation and a 5,000 m² pond treating 400 m3/d of domestic effluent.

The two stage reed bed system at Aumont (500 PE), in the French Jura mountains meets stringent discharge standards in phosphorous removal through a third stage filtration with reactive media

The municipal centralised treatment plant (a classic activated sludge technology) for the wastewater produced by the municipality of Jesi (Ancona province – central Italy) has been upgraded in the year 2002, with the realisation of a new “nitrification-denitrification” compartment and a hybrid Constructed Wetland as polishing stage. 

Castelluccio is one of the best hotspot of Central Italy, with its spellbound village and the great plateaus at 1400 m a.s.l. in the Sibillini mountain park. The new Constructed Wetland will treat the wastewater of Castelluccio village and tourism facilities, that progressively shift from less than 50 persons during winter up to 1000 or more persons during summer. The current treatment plant is inadequate to support this great variation. The new multistage CW system is constituted by a French scheme system of 1800 m2 followed by two parallel free water-pond system as polishing stage and recreational amenity (the pond will hold several rare aquatic plants typical of the Castelluccio plateau).

This wetland was built for groundwater remediation on the site of a former oil refinery at the State University of New York's Wellsville campus 2008

Allenwiller : a 1700 m², vertical flow reed bed (French system) plus a 960 m² second stage unsaturated vertical flow reed bed filter, treating 495 m3/d of domestic effluent from three villages (1100 PE) in Alsace.

Saint Bonnet le Froid : a 900 m², vertical flow reed bed (French system) plus a 600 m² second stage unsaturated vertical flow red bed for the treatment of  domestic effluent from a village with variable population.
